 ## Requirements:
 * A minetest version compatible with minetestmapper-numpy.py Made by Jogge, modified by celeron55
 * Python 2.7 (any 2.7.x)
-* Other requirements for Windows are below; other requirements for Ubuntu are installed by install-chunkymap-on-ubuntu.sh (for other distros, modify it and send me a copy as a GitHub issue as described below in the Installation section)

 ## Installation
 (NOTE: map refresh skips existing tiles unless you delete the related png and text files in your chunkymapdata folder)
-* change set-minutely-crontab-job.sh to replace "owner" with the user that has the minetest folder (with util folder under it, not .minetest)
+* If you are not using Ubuntu, first edit the installer for your distro (and please send the modified file to me [submit as new issue named such as: DISTRONAME installer except instead of DISTRONAME put the distro you made work])
-* Install the git version of minetest (or otherwise install 0.4.13 or other version compatible with the map generators used by chunkymap)

+	(since install-chunkymap-on-ubuntu.sh DOES replace "/home/owner" with current user's home in all chunkymap scripts in destination folder)  
+	then go to Terminal and run:

 * IF you are using a distro such as Ubuntu 14.04 where first line of /etc/crontab is "m h dom mon dow user command" then if you want regular refresh of map then run
 	(otherwise first edit the script to fit your crontab then)
